These two pieces are contube 37. l nected together by two screws 3 (Fig. 2). The operation is as follows: The appara- Within the support 2 is mounted the upper tus b eing inserted through the usual upper burner 4 provided with Athe cover 5 (of openings of the stove to be heated, the supcast iron) having the holes 6. The burner port 1 lies upon the upper plate ofthe stove 105 4 is supported by the base 1 by means of aV in lieu of the rings and lid which usually lug 7. close said openings, and the burners 29 are A grate 8 and two flat rings 9 and 10 thus disposed within the fire pot of the as well as a lid 11 (Fig. 1), are placed upstove. The gas admitted through the hose- 55 .ce the Support ,2, all these members being coupling 39 .enters the tube 37 and flows 110 through the cocks 18 and 36 either to the upperbu'rner 4 -or to the two lower burners 29.

The gas flowing through the coclr 36 reaches the central. injector 34 of the nut 3B and is injected into the burner 4, drawing in primary'aip coming from the outside and passing through an orifice in the support 2. The secondary air required for' the combustion of the gas discharged by the burner 4vco1ns from the ash pit of the Istove and passes through. the sleeves 14 and 13. The mixture of air and gas is discharged through the lioles 6 and the flames come directly into Contact 'with any articlelaid on the grate 8 the set of rings and lid 9, l0, and l1. The grate 8 allows the hot gases to flow around` an article to be heated whose diameter is`less than that of the grate. Notches areformedl at46 around the top edge of the support 2 in order to facilitate the circulationV of the hot gases when the article to be heated' hasI a vgreater diameter thanv that of the apparatus. 'Y

The gas, flowing through the cock 18, passes through the tubes and elbows 17. 16, 16a, 19. 20, 21, 22 and then through the plugs 23, and reaches the two injectors 26.l When issuing` from, each injector, the gasis mixed witlrthe air-coming from the ash-pit ot the stove and the combustible mixture, escapes through the crescent-shapedburners 29. The fiamesxare distributed through the notches 47f`provided in the burners 29. Said fiames wheat the wallsof the fire pot, in the same manner as withthe coal when coal is burned in the stove. The hot burnt gases produced bythe Vcombustion of the combustible mixture are thus caused to follow the same path yas thel gas produced by the combustion of coal, and the whole stove is thus heated. the draught of the' stove being used for the combustion of coal. Moreover the seconclary 'air required 'for the combustion of' the l lowerburner's coming from the ash pit, is heated by the contact with said burners and the verc'ess of air circulates with the hot burnt gases'l vproduced bythe combustion. Thisciijculation maybe regulated by acting` pnthe draught f the stove. l Y'Thecouplings 40l and 41 for the `gas feed may be'` t'lirnedin any convenient direction, and the same may as well bezplaced in place of lthe plug '38 according to the retpiirements` of 'the stove installation. 1

FigureA 3 shows the arrangement of the burners upon,` thewplugs 23. These latter arefcansedto;rotate' with the pipes 24, and the: 'holes of [the4 injectorsI `26n remain thus constantly o n ythe aXis'o't the vconduits f the pilvfs l24,',infspite.ofthis rotation. This devicel'y'vperi'rnitsof the two burners in any "posrlon"with l respect to each other. Eaphfburner'inaybe rotated vin a position comprised between 'that shown in full lines in Fig. 3 and that shown in full and dotted linesin'this figure at 29a. These positions of the burner will be of course in accordance with the width oi the fire pot and in such manner that the flames shall always be in contact with the walls of the latter.

By unscrewing the screw 15 (Fig. l) and screwing or unscrewing the piece 22, the burners 29 may be raised or lowered according` to the depth of the Alire pot in which the removable apparatus disposedQ The injectors are adjustable according to the pressiu'es or according to the desired outputs, by the useof theneedlevalves 27 and $3421.

The apparatus according yto the invention is very efhcient and also Yof a hygienic use since the discharge of the lburnt gases isyeffected through the chimney of thestove.

1. A gas burning device comprising a support, an upper burner ycarried port, means for supplying burner. a central vertical pipe depending from said support.r lower burners carried by said pipe at the lower end thereof and in communication therewith, and" means for changing` the length ofsaid pipe whereby the vertical distancebetween said upper and lower burners may beadjusted. 'i

2. A burning'device,comprising a support, an upper burner carried 'by said sup,

port, means for supplying gas to said upper burner, a central pipe secured toV said support and below the saine, a hollow'T-shaped member screwed on thef'lower end of said central pipe, two'plugs.. rotatablyf'mounted on the ends ofthe cross part of said member and provided with an axialV bore, a lower burner secured to'each Aof said plugs and in communication with the axialA bore'of the latter and means for supplying. gas to said central pipe. Y

4. A gas burning device comprisinga support, an upper burner carried by said support, means, for supplying gas to said upper burner, a central pipe secured to said sup-l port and below the same, a hollowA T-sha'ped member screwed cn the lower end of said central pipe, two plugs rotatably mounted on the ends of the cross part of said member and provided with an axial bore, a lower burner secured to each of said plugs and in communication with the axial bore of the latter, a sleeve o'f adjustable length carried by said support and surrounding said ceutral pipe and T-shaped member, said sleeve opening below the upper burner.

5. A gas burning device comprising a support, an upper burner carried by said support, means including an adjustable needle valve for supplying gas to said upper burner, a central pipe secured to said support and below the same, a hollow T-shaped member screwed on the lower end of said central pipe, two plugs rotatably mounted on the ends of the cross part of said member and provided with an axial bore, a lower burner secured to each of said plugs and in communication with the axial bore of the latter through the intermediary of an adjustable needle valve and means for supplying gas to said central pipe.

In testimony whereof I have signed my name to this specification.
